The calculation method of the elastic modulus of bell-shaped Metal Rubber（MR） isolator was investigated. The elasticity of the isolator under the shear and tension loading was obtained, and these parameters were used in the finite element analysis to study the deformation of the isolator. The results show that for a Metal Rubber isolator with a complex structure, the usage of the equivalent elastic modulus of the Metal Rubber material provides a simplified approach in the analysis of the vibration isolation performance, which is beneficial to the further research of Metal Rubber isolator.
